چکیده

The primary focus of this project is the analysis of data from the Philippine Sea (PhilSea) experiments in 2009-2011. Data from previous ONR-sponsored deep water experiments may also be analyzed. The specific objectives of the project are: 1) to characterize the ambient noise in the PhilSea data set using spectral analysis and to compare the results to those for other deep water data sets; 2) to analyze the acoustic modes in the ambient noise and moored source data sets acquired in the PhilSea experiments; 3) to implement tomographic inversions using mode signals from the PhilSea experiments.

Fundamental and higher-mode Rayleigh wave characteristics of ambient seismic noise in New Zealand

[1] In order to use ambient seismic noise for mapping Earth’s structure, it is important to understand the spatiotemporal characteristics of the noise field. This study uses data collected during four austral winter months of 2002 to investigate New Zealand’s ambient seismic noise field in the double-ocean-wave-frequency range (0.1–0.3 Hz). It is shown via beamforming analysis that there are tw...

Coral reef and tropical shallow water soundscapes

Much is known about deep ocean ambient noise, rather less about the more highly structured and variable noise in temperate coastal waters, and rather little about the tropical shallow waters that include coral reefs and the biological diversity these ecosystems support. Interest in shallow water acoustics has been growing over the last decade, and more recently specific interest has bloomed in ...

Low-frequency Broadband Noise Correlation Processing in Deep-water

Correlation processing of ocean ambient noise has been shown to reveal ocean environmental information. While theory confirms the efficacy of this procedure, experimental confirmation has been limited to either shallow water scenarios or the shipping noise regime. The basic issue of the potential utility of this procedure is the time needed to build up the relevant cross-correlation peaks that ...

Directionality of Ambient Noise on the Juan de Fuca Plate: Implications for Source Locations of the Primary and Secondary Microseisms

Based on cross-correlations of ambient seismic noise computed using 61 ocean bottom seismometers (OBSs) within the Juan de Fuca (JdF) plate from the Cascadia Initiative experiment and 42 continental stations near the coast of the western United States, we investigate the locations of generation of the primary (11–20 s period) and secondary (5–10 s period) microseisms in the northern Pacific Oce...

Wind-generated ambient noise in a shallow brackish water environment in the archipelago of the Gulf of Finland.

Underwater ambient noise measurements were carried out in a shallow (15-20 m) brackish water in the archipelago of the Gulf of Finland for period of 1 year. The absence of traffic noise made it possible to study wind driven effects in ambient noise at lower frequencies. The ambient noise comes mostly from local sources and the propagation effects are shown to be negligible. The ambient noise de...
